Abstract: ABSTRACT OF THE DISCLOSURE            In the illustrative embodiments of the invention disclosed, the lithology of an earth formation traversed by a well bore is investigated by irradiating the formation with a neutron source and generating an energy spectrum of the activation gamma rays resulting therefrom. From the spectrum thus obtained, the levelsof the activation gamma radiation emitted by 27Mg and that emitted by 49Ca are determined. The two intensity measurements are then combined, e.g. by forming a cross-plot or ratio thereof, to provide an indication of the lithology of the earth formation and, in particular, of the extent of dolomitization of the formation.

Abstract: ABSTRACT OF THE DISCLOSURE            A foam extrusion apparatus and method employs one or more extruders mounted on horizontal rails for movement toward and away from the end of a vacuum chamber which is in the form of an elongated inclined barometric leg. The upper end of the chamber is closed by two, substantially concentric in the closed position, substantial bulkheads, each also supported on rails and held in an inclined position to close the upper end of the chamber when moved, one against the chamber and the other against the one. A die is positioned on the inside of the other or smaller bulkhead and aligned with the leg when closed. The extruders are connected to the die through a length of pipe extending through the smaller bulkhead and sealed by a bellows. A shaping mechanism is supported on the interior of the one or larger bulkhead surrounding the die when both bulkheads close the upper end of the inclined barometric leg or vacuum chamber. The die is adjustable externally of the bulkhead. The extruders, die and bulkheads are movable as a unit or separately toward and away from each other to provide access to the die, to the shaping mechanism, and to the interior of the chamber.

Abstract: APPARATUS FOR MAINTAINING SYNCHRONISM OF AN INVERTER-SYNCHRONOUS MACHINE DRIVE SYSTEM AT LIGHT OR ZERO MACHINE LOADS                 ABSTRACT OF THE DISCLOSURE   To achieve synchronization of an inverter-synchronous machine drive system, feedback of a phase angle signal, derived in part from stator current drawn by, and voltage supplied to, the synchronous machine, is provided to control the frequency of inverter thyristor conduction. At light or zero synchronous machine load conditions, machine stator current may be of insufficient magnitude to permit derivation of the phase angle feedback signal; therefore, substitute simulated stator current signals, proportional to a preselected combination of inverter thyristor gating pulses, are utilized to derive the phase angle feedback signal, thereby allowing inverter-synchronous machine drive synchronism to be maintained.

Abstract: WORKPIECE ASSEMBLY MACHINERY                 ABSTRACT OF THE DISCLOSURE           A conveyor line moves palleted workpieces past a plurality of work stations arranged at intervals along the line.  The pallets to which the workpieces are clamped are frictionally supported for travel at a designated linear rate of speed.  A portion of the conveyor line ad-jacent one or more work stations includes a conveyor for spaced apart pallet control elements, which are driven at a reduced rate of speed.  The traveling pallet control elements on the second conveyor prevent the pallets from moving at the faster rate of the first conveyor.  A stop element, which is normally maintained in the path of pallets on the first conveyor but moves out of the plane of movement of the pallets to release the pallets indi-vidually is operated when a pallet control element on the second conveyor reaches a predetermined position.          The relative speed of these conveyors, the position of the stop element, and the spacing of the pallet control elements, is such that there is time before the release of a subsequent pallet for an assembler or operator to grasp and temporarily halt travel of a pallet to com-plete an operation before permitting it to resume its travel.  When the second conveyor control elements fin-ally release the pallets to travel at the speed of the first conveyor, they are in a predetermined, spaced apart relationship.

Abstract: RCA 72,789 Abstract of the Disclosure An arrangement for symmetrically gain controlling a differential amplifier is disclosed.  A control circuit including first and second similarly arranged transistors coupled between points of operating potential develops first and second control voltages of prescribed magnitude at collector outputs of the transistors.  The first transistor is biased to provide the first control voltage at a fixed, prescribed level related to the gain control bias requirements of the amplifier.  The second control voltage varies symmetrically with respect to the first control voltage in response to the setting of a poten-tiometer coupled to a bias circuit of the second transistor. The potentiometer is connected directly between points of operating potential such that the control voltages are equal for a center potentiometer setting, and the second control voltage varies symmetrically with respect to the first control voltage as the potentiometer is adjusted between minimum and maximum extremes to thereby produce symmetrical amplifier gain control.  Symmetrical gain control is predictable and independent of potentiometer tolerance effects and variations of the operating potentials associated with the control circuit.
